Apparatus and method for recognizing voice

摘要

An apparatus and a method for recognizing a voice include a plurality of array microphones configured to have at least one microphone, and a seat controller configured to check a position of a seat provided in a vehicle. A microphone controller is configured to set a beam forming region based on the checked position of the seat and controls an array microphone so as to obtain sound source data from the set beam forming region.

1. An apparatus for recognizing a voice, the apparatus comprising:
a plurality of array microphones configured to have at least one microphone; a seat controller configured to check a position of a seat provided in a vehicle; and a microphone controller configured to set a beam forming region based on the checked position of the seat and control the array microphones so as to obtain sound source data from the set beam forming region, wherein the microphone controller recognizes a total movement distance of the seat as a total beam forming angle of the array microphones, wherein the microphone controller divides the total movement distance of the seat equally into a plurality of sections and divides the total beam forming angle of the array microphones equally into a plurality of sections according to the divided sections to thereby form first beam forming sections, wherein the microphone controller sets a section corresponding to the seat position among the first beam forming sections as a first beam forming region, wherein the microphone controller divides the first beam forming region into a plurality of sections to thereby generate a plurality of second beam forming sections, and wherein the microphone controller compares each of the plurality of second beam forming sections and sets a section from which a signal having the largest strength is obtained among signals of sound source data obtained from a first array microphone and a second array microphone as a second beam forming region.
